This study focuses on the feasibility of using a crosslinked amidoximated copolymeric hydrogel as an adsorbent for recovering uranium and thorium ions from aqueous media. The hydrogel showed good adsorption capacity, which was influenced by the acidity and temperature of the medium.
This work focuses on investigating the feasibility of using a crosslinked amidoximated copolymeric hydrogel as a potential adsorbent to recover uranium and thorium ions from aqueous media. The hydrogel was synthesized via gamma-irradiation copolymerization and characterized through FTIR, TGA, and SEM. The medium acidity notably affected the adsorption capacity of both ions. The adsorption data was in line with the pseudo-1st-order equation and the Freundlich isothermal model. The thermodynamics analysis showed that the temperature rise promoted the adsorption capacity. The reusability studies highlighted the good performance of the hydrogel up to five regeneration rounds.
